Assessment of Available Manganese in Milk by Using fodders Grown in Long-Term Wastewater Irrigated Soil

Heavy metals are considered as most important contaminations due to industrialization of countries and an influence on its existence in soil, plant and milk. A study was carried out to check manganese content in soil, forage and milk at three sites of city Jhang, Punjab, Pakistan. All samples (milk, soil, water, fodder plants and ground water) were analyzed for manganese by Atomic Absorption Spectrophotometer. Different health indices were also studied to check Mn flow in food chain. Level of Mn in samples was found within acceptable limits. Manganese level was higher in soil samples collected from Site-III than other sites. Manganese showed higher value (2.595 to 10.402 mg/kg) in soil than other samples. Fodders were found to accumulate manganese from 0.008 to 0.022 mg/kg. Manganese concentration was found to be 0.1482 to 1.241 mg/L, 0.164 to 0.9708 mg/L in water and milk, respectively. BCF and PLI values for manganese were also found to be less than 1. Estimated daily intake (EDI) and THQ of manganese are found within permissible limits in milk of cows feeding on fodders irrigated with wastewater and ground water. So, use of wastewater for irrigation purpose should be properly checked due to possible toxic effects

Heavy Metal Accumulation in Goosefoot (Chenopodium album L.) Irrigated With Wastewater

Wastewater sources contain enormous amounts of nutrients for plant growth. This study aimed to define the metal accumulation in the goosefoot plant (Chenopodium album L.) of wastewater use in agricultural irrigation and to evaluate the risks of this accumulation to human health. The present research was performed in field conditions in Khushab, Pakistan. The Cd, Cu, Cr, Fe, Zn, Ni, and Mn concentrations were determined with the analysis performed using Atomic Absorption Spectrophotometer-AAS. Heavy metal concentrations in goosefoot samples irrigated with groundwater (GWI), canal water (CWI) and sugar mill water (MWI) ranged from 0.84 to 1.08, 0.55 to 0.78, 0.23 to 0.70, 2.09 to 5.56, 2.84 to 13.53, 0.53 to 1.13 and 0.32 to 0.39 mg/kg for Cd, Cr, Cu, Fe, Ni, Zn, and Mn, respectively. According to the statistical analyses, wastewater applications had a non-significant effect on Cr, Cu, and Zn concentrations in C. album samples collected from three sites, and a significant effect on Cd, Fe, Mn, and Ni concentrations (p>0.05). The results also showed that the health risk index value of cadmium was higher than 1. According to these results, long-term consumption of C. album samples grown in the study area may cause an accumulation of Cd in the human body and diseases in many tissues and organs

Impact of Wastewater and Canal Water Irrigation on the Accumulation of Copper in Maize and Millet of Different Districts of Punjab Pakistan

In current work, we examined the absorption of metal Copper in generally grown food crops (Maize & Millet), cultivated in the waste water irrigated different Districts of Punjab, Pakistan. Analyzed samples of Water, Soil, shoot and grain were processed through atomic absorption spectrometric method. Our findings of Copper in water and Shoot were highest for Millet of Sargodha, irrigated with wastewater (1.69 mg/kg and 1.43 mg/kg respectively). In soil and grain samples maximum absorption of Cu was obtained in the waste water irrigated Maize (Sargodha) and Millet (Sheikhupura). Overall, Cu level was within the acceptable parameters set by FAO/WHO (2001). In this study, we also find out different indices such as Enrichment factor, Translocation factor, Pollution Load Index, Bio-concentration factor, Daily intake of metal and Health Risk Index. The study determined that frequently intake of waste watered forages in experimenting zone may carry possible health uncertainties in inhabitants

Biomonitoring of Heavy Metal and Metalloid Contamination in Industrial Wastewater Irrigated Areas Using Sugar Beet (<i>Brassica oleracea</i> L.)

In Pakistan, wastewater such as industrial and urban wastewater is widely used for agricultural irrigation despite its chemical and pollutant content. In this respect, it is important to determine the risks of heavy metal accumulation in various agricultural products and the risks to human health. The aims of this study were to assess the heavy metal(loid)s contamination in soil and sugar beet samples and to assess the health risks of heavy metal(loid)s to the population via the consumption of sugar beet. The heavy metal(loid) values in the wastewater-irrigated soil samples ranged from 0.260 to 4.053 mg/kg, and wastewater-irrigated sugar beet samples ranged from 0.051 to 1.666 mg/kg. In contrast to Cd, Ni, Cu, Fe, Mn, Cr and Zn, which appeared to pose a health risk, Pb, Co, and Cr had Health Risk Index (HRI) values lower than 1.0 and did not appear to pose a threat to human health. Cd accumulation with HRI values over 1 (144.8) indicated that this metal is likely to have a major negative impact on local health

Arsenic and Cadmium Risk Assessment in a Domestic Wastewater Irrigated Area Using Samples of Water, Soil and Forages as Indicators

The recent research was performed to investigate the toxicity of As and Cd in suburban area of Sargodha, Punjab, Pakistan. Water, soil and forage samples were collected for this purpose in summer and winter season and analysis was done via wet digestion to determine the concentration of selected heavy metals. The mean concentration of As and Cd in water was found above the permissible maximum limit. Mean concentration of Cd in soil and forages was lower than the allowed limit whereas As which was higher than the PML in forages. So, continuous use of domestic wastewater for irrigation purpose should be avoided in order to secure the area from any hazard in near future

Toxicological potential of cobalt in forage for ruminants grown in polluted soil: a health risk assessment from trace metal pollution for livestock

The trace metal pollution in the environment is a highly concerned issue in these days. One of the important causes of trace metal pollution is the exhaust gases released from the vehicles on the roads. These dangerous gases pose life-threatening effects on the forage plants grown along the roadside as these plants are at direct risk to these trace metals. The aims of the present study were to determine the cobalt (Co) concentrations in soil, forages, and blood plasma of the buffaloes and to evaluate the Co deficiencies and toxicities in these samples. All samples were collected from six sites (Faisalabad roadside, Bhalwal roadside, Shaheenabad roadside, Mateela roadside, 50 Chak roadside, and Dera Saudi-control) of Sargodha city. The Co concentrations in these samples were determined by atomic absorption spectrophotometer (AA-6300 Shimadzu Japan). In soil samples, Co level ranged from 1.958 to 3.457mg/kg in the six sampling sites. The highest Co level was observed at site 6 and the lowest at site 2. In forage samples, Co level ranged from 0.770 to 2.309mg/kg in the six sampling sites. The highest Co level was observed at site 3 and the lowest at site 2. In blood plasma samples, Co level ranged from 2.644 to 4.927mg/kg in the six sampling sites. The highest Co level was observed at site 1 and the lowest at site 3. The results showed higher Co values in the samples collected from the site IV while the bioconcentration factor for forage-soil was found highest in the samples collected from Site III. On the other hand, a correlation was found positively significant when soil and forage were correlated, and it was found negatively significant when blood and forage were correlated

Risk Assessment of Heavy Metals in Basmati Rice: Implications for Public Health

Basmati rice is increasingly recognized and consumed in different parts of the world due to its different tastes and nutritional properties. This research focused on determining the cadmium (Cd), cobalt (Co), Copper (Cu), iron (Fe), manganese (Mn), nickel (Ni) and zinc (Zn) content in locally grown basmati rice in Pakistan and assessing the risks of these values to human health. Root, shoot and grain samples of basmati rice were taken, along with soil samples from the five regions studied. Metal mean concentrations (mg/kg) in grains fluctuated from 2.70 to 9.80 for Cd, 4.80 to 9.85 for Zn, 1.16 to 1.46 for Cu, 1.84 to 10.86 for Co, 2.05 to 13.07 for Fe, 5.03 to 11.11 for Mn and 3.24 to 13.28 for Ni, respectively. All metal values were within permissible limits except for Cd. The enrichment factor for Cd was highest among all sites. Cobalt and zinc had the highest bioaccumulation factor and translocation factor. The highest enrichment factor was noticed for Cd and the lowest for Cu. The health risk index at all examined sites was less than one. Consistent examination is recommended to limit health hazards instigated by the use of rice polluted with a greater concentration of Cd

Estimation of Chromium in Soil-Plant-Animal Continuum: A Case Study in Ruminants of Punjab, Pakistan

The increased use of waste water for agriculture purposes has increased around the globe. There are toxic metals present in waste water which affect plants, animals and human health. But at the same time it also contains useful nutrients which increase growth of plants. Different indices were applied to evaluate the metals present in water soil plant and milk. Various and correlation were determined with the help of SPSS, mean significance was found at the probability levels of 0.05, 0.001 and 0.01. The highest value of Cr was found in Avena sativa (0.7872 mg/kg) collected from site 5 while lower concentration of Cr was observed in Brassica campestris (0.0743 mg/kg) at site 4. In soil samples, Trifolium alexandrinum showed highest value of Cr (0.9887 mg/kg) at site 1 while lowered concentration was observed in Zea mays (0.1862 mg/kg) at site 3. Milk samples of site 5 had higher value of Cr (0.2898 mg/kg) and lowest at (0.1540 mg/kg) site 2. Water samples of site 3 had high value of Cr in them (1.849 mg/kg) and lowered concentration was found in water samples of site 5 (0.219 mg/kg). Cr concentration in fodders ranges from 0.0743 to 0.7872 mg/kg, soil 0.1862 to 0.9887 mg/kg, milk 0.1540 to 0.2898 mg/kg and water 0.219 to 1.849 mg/kg. In water samples, Cr level were above than permissible limit. In milk samples, concentration of Cr was greater than permissible limit which shows that it is hazardous to human health, may be due to pollution of environment like air, water and soil. This study concluded that if animals are allowed to graze on contaminated fodders and drink wastewater then metals were accumulated in their tissues and milk which causes toxicity to human health
