“…Observed removal rates of chlorinated pesticides ranged from 98.4% to 99.7% in the presence of high salt content. The separation efficiency was slightly higher for DDT and its derivatives than for HCH isomers [100].…”

“…Šír et al [100] also started work on the removal of chlorinated pesticides, mainly α-HCH, β-HCH, γ-HCH, HCB, DDE, DDD, and DDT from groundwater. A LAB M-20 membrane, a small-scale separation test unit, with a LabStack M20 membrane module, with a nominal capacity of 30 dm 3 /h, at a maximum pressure of 6.0 MPa, was used for the tests.…”

Chemical, biological, radiological, or nuclear (CBRN) contamination of the environment is a significant threat to human health and life as well as environmental safety. It is then necessary to take actions aimed at minimizing and eliminating the threat. Depending on the type of contamination, various methods are used, including sorption, biodegradation, separation, or ion exchange processes in which membranes play an important role. The type of membrane is selected in respect of both the environment and the type of neutralized pollutants. Therefore, the production and modification of membranes are being adapted to the type of contamination and the purpose of the work. This article presents examples of membranes and their possible applications depending on the part of the environment subject to reclamation and the type of contamination.

“…Reverse osmosis (RO) technology has been used for ground water treatment contaminated with organochlorines. Membranes used were of RO98pHt polyamide, and removal rate was observed to be 98.4-99.7% for pesticides, and dissolved solids were reduced from 1.35 g/dm 3 to less than 0.05 g/dm 3 [18]. Coupling of electrodialysis to desalinate wastewater and nanofiltration could improve the retention of pesticides on NF membranes [19].…”

Pesticides are a class of xenobiotic compounds that are recalcitrant and show persistence in the environment for a longer period of time. Research studies have linked their potential for mutagenicity, teratogenicity, and carcinogenicity. The accumulation of pesticides in water sources due to runoff from agricultural lands has posed a serious threat to the biota of the water ecosystem as well as to the human population. Long-term exposure to pesticides can cause neurological disorders, reproductive complications, cancer, immunological, and pulmonary diseases. The use of pesticides has dramatically surged in agricultural as well as nonagricultural practices. Tons of pesticides are applied in the fields, but a limited amount reaches to the target organism while the rest is wasted and gets accumulated in soil or ends up in water sources like groundwater or river, which results in eradication of nontarget organisms. A variety of pesticides are used for pest management, such as organochlorine (DDT), carbamates (carbaryl), organophosphates (malathion), and pyrethroids (pyrethrins). These chemicals are highly toxic to flora and fauna because of their nonbiodegradable and persistence nature. Biomagnification of pesticides usually leads to cause various problems in human beings. Organochlorines like DDT have been banned in many developed countries due to these reasons. Therefore, the removal of pesticides from wastewater and natural water sources is of utmost importance. Conventional methods possess various limitations; therefore, there is a requirement of an alternative method which can efficiently remove these pollutants from the wastewater. In this review, environmental impacts and health-related complications of pesticides and microbial remediation approaches and use of different nanomaterials in the pesticide removal have been discussed.
