Impact of Pesticides as Organic Micro-Pollutants on the Environment and Risks for Mankind

Bozoglu, Faruk
Because of health concerns, persistence, and long-term environmental effects, the impact of pesticides on agriculture and public health has been the subject of considerable research. Organophosphorus pesticides exert their acute effects by inhibiting acetylcholinesterase in the nervous system with subsequent accumulation of toxic levels of acetylcholine. Herbicides have widely variable toxicity. In addition to acute toxicity from high exposures, there is concern over possible carcinogenicity as well as other long-term problems. Improper use of herbicides may damage crop plants, especially if too large a dose is used, or if spraying occurs during a time when the crop species is sensitive to the herbicide. There are also apprehensions about the toxicity of some herbicides, which may affect people using these chemicals during the course of their occupation. The use of herbicides and other pesticides carries risks to humans through exposure to these potentially toxic chemicals, and to ecosystems through direct toxicity caused to non-target species, and through changes in habitat. People exposed to pesticides had over a fourfold increased risk to Non-Hodgkin's lymphoma (NHL), neuroblastoma, child brain development defects, Parkinson's disease, prostate cancer, leukemia in children, male infertility and miscarriage.


Investigation of adsorption of pesticides by organo-zeolite from wastewater
Lüle, Güzide Meltem; Atalay, M Ümit; Özbayoğlu, Gülhan; Department of Mining Engineering (2011)
The aim of this study was to determine the adsorption capacity of activated carbon and organo-zeolites for removal of pesticides in water. In order to prepare organo-zeolite, two kinds of cationic surfactants, namely, hexadecyltrimethyl ammonium bromide (HTAB) and dodecyltrimethyl ammonium bromide (DTAB) were used. Adsorption studies of cationic surfactant on zeolite were investigated in respect to initial concentration of cationic surfactant, time, and temperature. It has been found that the best fitted is...
Identification of specific pollutants in Yeşilırmak river basin by using COMMPS and NORMAN prioritization methods
Erciyas, Emre; Yetiş, Ülkü; Department of Environmental Engineering (2018)
According to the Water Framework Directive (2000/60/EC), there is a need for the identification of substances posing a relatively higher risk to the aquatic environment and human health to be included in monitoring and risk assessment studies. Thus, river basin specific pollutants must be identified and regularly monitored by the EU Member States to achieve good ecological water status. This study aims to determine specific pollutants in the Yesilirmak River Basin. The national list of 250 river basin speci...
Probabilistic-fuzzy health risk modeling
Kentel Erdoğan, Elçin (2004-10-01)
Health risk analysis of multi-pathway exposure to contaminated water involves the use of mechanistic models that include many uncertain and highly variable parameters. Currently, the uncertainties in these models are treated using statistical approaches. However, not all uncertainties in data or model parameters are due to randomness. Other sources of imprecision that may lead to uncertainty include scarce or incomplete data, measurement error, data obtained from expert judgment, or subjective interpretatio...
Effect of initial COD concentration, nutrient addition, temperature and microbial acclimation on anaerobic treatability of broiler and cattle manure
Gungor-Demirci, G; Demirer, Göksel Niyazi (2004-06-01)
In this study, anaerobic treatability and biogas generation potential of broiler and cattle manure were investigated. For this purpose, seven sets of anaerobic batch reactor experiments were performed using broiler and cattle manure and their mixtures in five different ratios (100% broiler; 75% broiler, 25% cattle; 50% broiler, 50% cattle; 25% broiler, 75% cattle; 100% cattle). These manure mixtures had two different initial chemical oxygen demand (COD) (12,000 and 53,500 mg/l) concentrations. The effects o...

Anaerobic digestion (AD) is a common method used for treatment of complex wastes with additional benefit of biogas production. Yet, the process has several limitations such as slow kinetics, long start-up periods and low methane (CH4) production yield. With the integration of microbial electrolysis cells (MECs) into AD, it is anticipated that these limitations of AD will be reduced. The reasons of such improvements in the AD-MEC integrated systems may stem from the enhanced electron transfer in microbial co...
