Widespread use of pesticides globally has led to serious concerns about environmental contamination, particularly with regard aquatic and soil ecosystems. This work involved investigating concentrations 64 in surface-water samples collected four provinces along the Mekong River Cambodia during dry rainy seasons (276 total), conducting semi-structured interviews local farmers pesticide use. Furthermore, an ecological risk assessment detected was performed. In total, 56 were surface water 43 soil, individual reaching maximum 1300 ng/L (tebufenozide) 1100 ng/g weight (bromophos-ethyl).

Mulching with plastic sheeting, the use of carriers in seed coatings, and irrigation wastewater or contaminated surface water have resulted plastics, microplastics, becoming ubiquitous agricultural soils. Once environment, surfaces quickly become colonised by microbial biofilm comprised a diverse community. This so-called 'plastisphere' community can also include human pathogens, particularly if has been exposed to faecal contamination (e.g., from organic manures livestock faeces). The plastisphere is hypothesised facilitate survival dissemination therefore plastics systems could play significant role transferring pathogens crops, as microplastics adhering ready eat crops are difficult remove washing. In this paper we critically discuss pathways for associated interact crop leaves roots, potential transfer, adherence, uptake plants. Globally, concentration soils increasing, therefore, quantifying transfer into food chain needs be treated priority.

Abstract The growing worldwide environmental and water pollution challenges require the use of renewable biomass-based materials to purify systems. remarkable qualities nanocellulose (NC) its eco-friendliness make it a desirable material for this purpose. Hence, many investigations have been conducted on optimization NC-based purification. This review presents first examination progress made in creating emerging NC composites using molecularly imprinted polymers (MIPs), metal organic frameworks (MOFs), aluminosilicates. MIPs, MOFs, aluminosilicates endow with stability, multifunctionality, extended reusability. applications these wastewater treatment, such as removal toxic heavy metals, dyes, pharmaceuticals, microorganisms are discussed. Finally, economic viability, challenges, future perspectives their research gaps demonstrated will enable exploration new areas study functionalised composites, leading enhanced industrial applications. Moreover, utilisation suitably modified components results multifunctional adsorbents that great potential effectively eliminating contaminants simultaneously.
