“…Increased catalase activity and altered antioxidant capacity against peroxides (ACAP) and thiobarbituric acid reactive substances (TBARS) confirmed the oxidative stress in the brain, gills, muscle and liver of the tested fish ( Marins et al, 2021 ). Gonçalves et al (2018) evaluated the oxidative stress biomarkers in the muscle, brain, gill and liver of Astyanax jacuhiensis in exposure to carbamate propoxur. There was an increase in the activity of GST in the liver and gills and protein carbonyl (PC) in the brain, whereas AChE activities were reduced in the brain and muscle.…”

Microplastics and pesticides are emerging contaminants in the marine biota, which cause many harmful effects on aquatic organisms, especially on fish. Fish is a staple and affordable food source, rich in animal protein, along with various vitamins, essential amino acids, and minerals. Exposure of fish to microplastics, pesticides, and various nanoparticles generates ROS and induces oxidative stress, inflammation, immunotoxicity, genotoxicity, and DNA damage and alters gut microbiota, thus reducing the growth and quality of fish. Changes in fish behavioral patterns, swimming, and feeding habits were also observed under exposures to the above contaminants. These contaminants also affect the Nrf-2, JNK, ERK, NF-κB, and MAPK signaling pathways. And Nrf2-KEAP1 signalling modulates redox status marinating enzymes in fish. Effects of pesticides, microplastics, and nanoparticles found to modulate many antioxidant enzymes, including superoxide dismutase, catalase, and glutathione system. So, to protect fish health from stress, the contribution of nano-technology or nano-formulations was researched. A decrease in fish nutritional quality and population significantly impacts on the human diet, influencing traditions and economics worldwide. On the other hand, traces of microplastics and pesticides in the habitat water can enter humans by consuming contaminated fish which may result in serious health hazards. This review summarizes the oxidative stress caused due to microplastics, pesticides and nano-particle contamination or exposure in fish habitat water and their impact on human health. As a rescue mechanism, the use of nano-technology in the management of fish health and disease was discussed.

“…It is used in fruit, vegetable, corn, soybean, rice and other crops, as well as in food storage areas, households and domestic animals. [20][21][22] The results of the first campaign (C1), carried out in the rainy season, where rice cultivation predominates in the region, revealed the propoxur active principle in all sample points. In points 4, 6, and 7, they were quantified at a concentration of 0.025 μg L À 1 .…”

“…[23] The active ingredient found in this work does not have its use authorized by the European Union, [18] but has its use authorized for certain crops in Brazil. [21,30] It can be observed that some active ingredients of several pesticides do not have limit values established by Brazilian legislation, while it is known that a large number of substances are used in the country. For propoxur, there is no established value in the country.…”

Determination of Carbamates and Thiocarbamates in Water, Soil and Sediment of the Formoso River, TO, Brazil

Considering the increase in agricultural production in Brazil, the use of pesticides for this production, and that there are no studies on pesticides in the region, the presence of carbamates and thiocarbamates was investigated in different environmental compartments of the Formoso River, TO, Brazil, by UHPLC/MS/MS. The collections were made on the banks of this river, in the area of influence of the agricultural project. The active principles were not found in the soil and sediment samples, only the propoxur principle was found in the water, reaching values of up to 0.025 μg L À 1 . It was found that the biodiversity of the Tocantinense savannah is under threat, because even though only one of the substances surveyed, propoxur and its derivatives, has been detected, they are substances of high toxicity and tendency to contaminate surface and groundwater to varying degrees and irreversible damage to different species.
