Elemental hydrochemistry assessment on its variation and quality status in Langat River, Western Peninsular Malaysia.

This paper discusses the hydrochemistry variation and its quality status in Langat River, based on the chemistry of major ions, metal concentrations and suitability for drinking purposes. Water samples were collected from 30 different stations to assess their hydrochemical characteristics. The physico-chemical parameters selected were temperature, electrical conductivity, total dissolved solids (TDS), salinity, dissolved oxygen , pH, redox potential, HCO3, Cl, SO4, NO3, Ca, Na, K, Mg, 27Al, 138Ba, 9Be, 111Cd, 59Co, 63Cu, 52Cr, 57Fe, 55Mn, 60Ni, 208Pb, 80Se and 66Zn to investigate the variation of the constituents in the river water. Most of the parameters comply with the Drinking Water Quality Standard of the World Health Organization and the Malaysian National Standard for Drinking Water Quality by the Malaysia Ministry of Health except for EC, TDS, Cl, HCO3, SO4, Na, Mg, Al, Fe and Se. The results show that the Langat River is unsuitable for drinking purposes directly without treatment

AZERBAYCAN’IN MONOGRAFLARA GİREN ŞİFALI BİTKİLERİ

Bitkilerden yararlanma, insanlık tarihi kadar eskidir. İlkçağlardan beri insanlar çevrelerindeki bitkileri kullanarak dertlerine şifa aramışlardır. Faydalı gördükleri bitkileri tanımış, tanıtmış ve hastalıkların tedavisinde kullanmıştır. Son yıllarda sentetik ilaçların yan etkilerinin artması, insanları tekrar doğal veya kültürel ortamlarda yetişen bitkilerle tedaviye yöneltmiştir. Yöresel halk ilacı olarak kullanılan bitkilerin incelenmesi ve bunlar üzerinde daha ileri araştırmaların yapılması tedavide önemli olabilmektedir. Bu nedenle değişik bölgelerde halk ilacı olarak, birçok bitki değerlendirilmektedir

SECRET BEAUTY OF FRESHWATER: ‘‘AQUARIUM MOSSES’’

Bryophytes are the oldest of all land plants and are believed to be the closest remaining linkbetween land and aquatic plants. Their soft tissue makes fossil records bleak but the oldest evidencethat has so far been found can be dated back to almost 500 million years ago. Spore-like structures ofa liverwort were found in Argentinian rock dated to 473-471 million years old. The first evidence ofmosses appears much more recently between fossils aged between 299-250 million years old. Due tothe poor preservation of Bryophyte species, it is quite possible that the Bryophytes are significantlyolder.The bryophytes are the second largest group, exceeded only by the Magnoliophyta – theflowering plants (350,000 species). Their nearest algal relatives appear to be members of theCharophyta. Bryophytes are generally considered the first land plants. The role of bryophytes in theecosystem is significant despite their small size.Aquatic mosses are generally chosen for their aesthetic qualities; they can also contribute toimproved water quality. As photosynthesizing plants, aquatic mosses absorb nutrients in youraquarium water, including nitrates, from the water column. Where other plants require high lightlevels to accomplish this, or a regular fertilizing regime, aquatic mosses are effective nitrate removerswithout high light levels or fertilizer.Bryophytes are the oldest of all land plants and are believed to be the closest remaining linkbetween land and aquatic plants.

ALGAE AND DIETARY DIETS

Algae involve several species of multicellular and macroscopic marine algae found in the coastal region between high to low tide in the sub-tidal region up to a depth where 0.01 % photosynthetic light is available. Based on their pigmentation, seaweeds were classified in to Chlorophyta (green algae), Phaeophyta (Brown algae) and Rhodophyta (Red algae). Algae are not classified as true plants. They lack an organized vascular system for absorbing nutrients. The root called the holdfast, the stem is the stripe and the leaf of the seaweed is the blade or frond. Like flowering plants, they are able to use chlorophyll to conduct the process of photosynthesis and create their own food for growth. In marine ecosystems, macroalgae communities provide nutrition, reproduction, and an accommodating environment for other living organisms. Algae play a vital role in various aspects compared to other aquatic resources. Because of these properties, macroalgae are some of the most important organisms maintaining the ecosystem’s stability. They are also excellent source of bioactive compounds such as carotenoids, dietary fibers, proteins, essential fatty acids, vitamins, minerals and important sources of medicines and fertilizers.     &nbsp

New national and regional bryophyte records, 36

In the moss flora of Uruguay there are recorder ten species of genus Fissidens (Matteri, 2004). Three of them (F. macrobryoides, F. prionocheilos and F. vitreo-limbatus) are species incertae because the type material for the names not was located (Purssel, 2007). As part of project "Studies on Bryophytes in the Cone Sur (Systematic and Phylogeny)" some specimens recently collected in Uruguay were determinate as Fissidens asplenioides a no previously species recorded in this country. The presence of F. asplenioides in Uruguay complete the distribution range of the species in the cone Sur (is present in Argentina, Bolivia, Brazil, Chile and Paraguay). However, within the Neotropical region there are few records of F. asplenoides in the phytogeographic province of Pampa. In Uruguay, where other bryophytes were recently recorded (Ellis et al., 2011, 2012a, b), F. asplenioides was collected in the river on semi-submerged rock.Fil: Ellis, L. T..
