“…Dissolved oxygen concentration remained quite low in the analyzed treatments, likely due to low water depth (15 cm). Other authors also reported low dissolved oxygen concentration in areas planted with rice and subjected to pesticide applications (GOLOMBIESKI et al, 2008;REIMCHE et al, 2008;BAUMART et al, 2011). 2003;DI GIOVANNI et al, 1996).…”

This study evaluated changes in the composition of the benthic community of non-target organisms in rice crop fields due to residual effect one year after planting seeds treated with different Fipronil doses. Macroinvertebrates were collected during crop irrigation months (February, March and April/2012), with the aid of 1 mm hand net placed close to the ground of each plot, for 20 minutes, collected macroinvertebrates were classified according to its dietary habits function. Orizophagus oryzae larvae, the target organisms, were not found in groups treated with different Fipronil doses; they were only observed in the control treatment. Chironominae (Chironomidae: Diptera) larvae had their population reduced in comparison to the control treatment. However, the herein used insecticide doses did not show significant changes in the benthic macroinvertebrate community one year after their application.

“…A less significant degradation pathway of carbofuran is through the photolysis reaction. Carbofuran is not likely to accumulate in sunlight-exposed water and does not bioaccumulate (Baumart et al, 2011). The metabolic product of photolysis includes (Evert, 2002) 2,3-dihydro-2,2 dimethyl benzofuran-4,7-diol and 2,3-dihydro-3 keto-2,2 dimethyl benzofuran-7-yl carbamate (3-ketocarbofuran) (Mahalakshmi et al, 2007;Remucal, 2014).…”

Pesticides are commonly applied in agriculture to manage pests, parasites, weeds, and other crop diseases to maximise product output value and minimise or reduce yield losses. Pesticides are widely and indiscriminately used in crop production in most countries. Carbofuran is a highly toxic insecticide commonly used to protect crops in agricultural areas. Exposure to carbofuran can cause harmful effects on both the ecological environment and human health, particularly on non-target species such as birds and aquatic organisms. Carbofuran continues to be used, although it has been banned in some countries. This review paper highlights carbofuran usage, its residue, toxicity, and mechanisms of degradation pathways in water, soil, and food, especially in agriculture. It has been shown that hydrolysis, photolysis, and microbial degradation are the main pathways for carbofuran degradation. Carbofuran phenol is significantly less toxic than all photo-metabolites, while 3-ketocarbofuran and 3-hydroxycarbofuran are practically as harmful as the parent compound. Hence, more study is needed on degradation pathways that may thoroughly minimise the toxicity of this deadly pesticide.

“…Rice crops in majority are inserted in lowland areas, areas located close to watercourses and ground water. In this sense, studies analyzing residues of pesticides in irrigation water are also relevant, since the contamination of water sources may occur as a result of management practices and extravasation of irrigation water (Rodrigues et al, 2013), may reflect negatively on water quality, and thus present health risks to non‐target organisms, such as zooplankton community (Golombieski et al, 2008), benthic macroinvertebrates (Mize et al, 2008; Baumart et al, 2011), fish (Hussar et al, 2004; Nakagome et al, 2007; Toni et al, 2011) and also interfere in the quality of drinking water (Narita et al, 2014).…”

e use of pesticides assists in integrated programs that aim high yield and quality grains in irrigated rice (Oryza sativa L.). However, the use of pesticides can pose risk to rice quality as well as the environment and general population. erefore, the objective of this study was to investigate the dissipation and persistence of fungicides (azoxystrobin and difenoconazole) and the insecticides (lambda-cyhalothrin and thiamethoxam) in irrigation water, soil, rice plant, panicle, and rice grain. e study was conducted in the eld during the 2011/2012 crop season, with fungicides and insecticides applied to the aerial parts of the rice plants, the samples were collected in di erent moments during a 40-d monitoring period a er the application of the pesticides. Laboratory analyses to detect pesticide residues were determined by ultra-high performance liquid chromatography and by gas chromatography. Pesticide residues were detected in irrigation water and rice plants during the 40 d of monitoring. Azoxystrobin, difenoconazole, and thiamethoxan were transported into the environment due to over owed water from the rice eld, however pesticide residues were not detected in soil. Azoxystrobin, difenoconazole, thiamethoxan, and lambda-cyhalothrin residues were detected in rice hull, however, no residues were detected in neither brown nor polished rice grain.
