A simple, reproducible, environmentally friendly cellulose acetate modified glassy carbon electrode was prepared and used for the direct reduction of lindane in aqueous alcoholic medium. This modified electrode offers a high sensing current with a lower reduction potential for lindane. The lowest adsorption of pesticide molecules was observed on the cellulose acetate modified electrode when compared with a bare glassy carbon electrode which enhances the sensitivity of the sensor. This modified electrode is highly stable with respect to time, so that the single electrode can be used for the multiple analysis of the lindane sample. Cyclic voltammetry, differential pulse voltammetry and amperometry were used as the sensing techniques. The reduction potential of lindane on this modified electrode is À1.5 V whereas the reduction potential of nitropesticides is around À0.600 V. This wide difference in reduction potential can be used to estimate lindane even in the presence of nitropesticides by cyclic voltammetry and differential pulse voltammetry. The analytical utility of the proposed method was checked with a commercial lindane lotion and drinking water samples. An amperometric instrument, interfaced with the cellulose acetate modified glassy carbon electrode was designed and tested for the sensing of lindane. The performance of this instrument was assessed.

“…For instance, pesticides that are incorporated into the soil are less exposed to volatilization and runoff than pesticides applied on the surface of the soil (Larson et al 1995). Pesticides applied on plants are subject to washoff, photodegradation, and plant absorption, whereas pesticides in the soil are not (Calvet et al 2005;Galiulin et al 2002;Norris 1974). Pesticide distribution at field scale determines the pathways of the pesticide to the catchment outlet.…”

Pesticides are now occurring worldwide in almost all water resources, thus threatening the health of humans and other life. As a consequence, there is a strong social demand for designing safe cropping systems with less or no hazardous pesticides. Safe cropping systems can be designed now using pesticide transfer models. These models are mathematical tools that allow to predict the flow and concentration of pesticides in a field or a watershed. Here, we review the effects of agricultural practices on runoff, leaching, erosion, and drift from eight watershed models and nine field models. Our main findings are the following: (1) though models claim they account for practices, their effects cannot be represented. We present a method and four practice levels to assess the effects of practices in models, using tillage as an example. (2) The conceptual structure of the model highly influences the predicted distribution and transfer of pesticides. For instance, the pesticide levels remaining on the soil surface after plowing ranges from 0 % of the dose applied for the MIKE SHE-DAISY model to 100 % for GLEAMS, annAGNPS, SoilFug, and PestLCI. Only the Root Zone Water Quality Model (RZWQM) simulates pesticide interception by mulch during pesticide application. (3) Models should better take into account mulching, e.g., plastic, crop residues and associated crops, and other innovative practices. (4) A change in scale is needed for drift in watershed models. Here, topological watershed representations are the most promising way for upscaling the effects of practices. (5) Nonconservative calculations of pesticide interception by watershed mitigation structures (SWAT) should be carefully checked because these calculations underestimate the risk of pollution at the outlet. How models simulate practices will no longer be a secret for model users who apply our methodology and recommendations when selecting a model. We provide recommendations for improving tools to assess practices.

“…The finely dispersed part of the bottom sediments is a good adsorbent and deposit medium for various elements. At the same time, such sediments themselves become sources of secondary pollution of the bottom water layer and substrate on which coastal organisms live [3]. This means that sediments are included in the food chain of bottom organisms.…”

The work presents the results of quantitative assessment of heavy metals (HM) content in bottom sediments of the coastal zone near the Karadag nature Reserve. The data were obtained as a result of field studies in 2016-2018. Estimated СС and Cо coefficients and Zc were calculated. It was shown that arsenic concentration limits were exceeded everywhere in the samples. The nickel, lead, copper and zinc limits were found to have been exceeded in some locations. Ecological and geochemical assessment of water and bottom sediments quality in the section of Karadag water area has been made.
