Multi-residue pesticides analysis in water samples using reverse phase high performance liquid chromatography (RP-HPLC)

India is one of the leading suppliers of agrochemicals and has the largest pesticide industry in Asia. Among various Indian states, Punjab is the primary user of pesticides. Presence of pesticide residue in water and food products of Punjab is well documented. The present study was designed to envisage the level of pesticide contamination in pond water of eleven villages of Amritsar district of Punjab, India. A rapid and concurrent method for the identification and quantification of pesticides in water samples was developed and validated. The method validation parameters exhibited high sensitivity of the developed method and the proficiency for the identification and quantification of pesticide residues in water samples. The RP-HPLC method described here • is a novel method which is applicable for simple, rapid and precise detection of pesticides. • 40.02% of water samples were found contaminated with multi-residue pesticides. • carbofuran was the most abundant pesticide which was present in 18.18% samples.

Microplastic Pollution: An Emerging Threat to Terrestrial Plants and Insights into Its Remediation Strategies

Microplastics (MPs) are ubiquitous and constitute a global hazard to the environment because of their robustness, resilience, and long-term presence in the ecosystem. For now, the majority of research has primarily focused on marine and freshwater ecosystems, with just a small amount of attention towards the terrestrial ecosystems. Although terrestrial ecosystems are recognized as the origins and routes for MPs to reach the sea, there is a paucity of knowledge about these ecological compartments, which is necessary for conducting effective ecological risk assessments. Moreover, because of their high persistence and widespread usage in agriculture, agribusiness, and allied sectors, the presence of MPs in arable soils is undoubtedly an undeniable and severe concern. Consequently, in the recent decade, the potential risk of MPs in food production, as well as their impact on plant growth and development, has received a great deal of interest. Thus, a thorough understanding of the fate and risks MPs, as well as prospective removal procedures for safe and viable agricultural operations in real-world circumstances, are urgently needed. Therefore, the current review is proposed to highlight the potential sources and interactions of MPs with agroecosystems and plants, along with their remediation strategies
