“…Thus, the LC50;7d was considered higher than 118.0 mg L -1 for these herbicides, which were classified as practically non-toxic (USEPA, 2017). The results presented by W. brasiliensis were similar to those of L. trisulca exposed to 3.0 mg L -1 of 2,4-D, showing no intoxication effect (Belgers et al, 2007) and A. caroliniana with a LC50;7d higher than 118.0 mg L -1 (Silva et al, 2012) LC50;7d = 100.0 mg L -1 of atrazine, bentazone + imazamox, and clomazone (Della Vechia et al, 2016).…”

“…For these herbicides, W. brasiliensis was less sensitive than L. minor, with EC50 of 0.80 mg L -1 of metsulfuron-methyl (Cedergreen et al, 2004), atrazine with LC50;7d of 5.27 mg L -1 , and bentazone + imazamox (31.58 mg L -1 ) and clomazone (10.23 mg L -1 ) for L. minor (Della Vechia et al, 2016), and atrazine with EC50 of 31.5 μg L -1 for L. gibba (Lewis and Trusby, 2018).…”

This study aimed to establish the mass cultivation of Wolffia brasiliensis under laboratory conditions, determine the sensitivity of reference substances (potassium dichromate, sodium chloride, and potassium chloride), and estimate the acute toxicity (LC50;7d) for the herbicide glyphosate, diquat, paraquat, imazapyr, 2,4-D, saflufenacil, imazamox, penoxsulam, metsulfuron-methyl, and atrazine. Three media were tested for culture establishment: Hoagland’s medium, 5.0 g L-1 NPK fertilizer (20-5-20), a mixture of Oxisol + organic substrate of decaying aquatic plant (2:1; v v-1). Sensitivity tests with reference substances and acute toxicity for herbicides were carried out after establishing the cultivation. The species W. brasiliensis presented an excellent sensitivity response to reference substances, with means of LC50;7d of 15.61±2.13 g L-1, 17.02±0.50 g L-1, and 52.54±4.27 mg L-1 for sodium chloride, potassium chloride, and potassium dichromate, respectively. The acute toxicity response indicated that W. brasiliensis was extremely sensitive to diquat (LC50;7d = 0.07 mg L-1) and paraquat (LC50;7d < 0.05 mg L-1), sensitive to imazapyr (LC50;7d = 21.10 mg L-1), and little sensitive to the other herbicides. The response capacity for the different groups of herbicides, the standardized response to reference substances, and ease of cultivation in the laboratory indicate the potential for using this aquatic plant in the assessment of herbicide risk in aquatic environments.

“…The global consumption of pesticides should be emphasized because the global market represents about $ 40 billion per year . Pesticides cause numerous problems for the environment and human health, as well as causing resistance in many cases . A new generation of pesticides, precocenes, belonging to the proallatotoxins family, has recently emerged.…”

From Conventional Lewis Acids to Heterogeneous Montmorillonite K10: Eco‐Friendly Plant‐Based Catalysts Used as Green Lewis Acids

The concept of green chemistry began in the USA in the 1990s. Since the publication of the 12 principles of this concept, many reactions in organic chemistry have been developed, and chemical products have been synthesized under environmentally friendly conditions. Lewis acid mediated synthetic transformations are by far the most numerous and best studied. However, the use of certain Lewis acids may cause risks to environmental and human health. This Review discusses the evolution of Lewis acid catalyzed reactions from a homogeneous liquid phase to the solid phase to yield the expected organic molecules under green, safe conditions. In particular, recent developments and applications of biosourced catalysts from plants are highlighted.

In this sense the objective of assessing the levels of pesticide poisoning in rural farmers of San Sebastian and take AL, using acetylcholinesterase enzymes Erythrocyte and plasma as biological indicator of intoxication. This is a prospective, transversal and descriptive variables analyzed were: year whose, sex, age group, education, location, condition, route of exposure. The data were acquired by collecting blood samples and socio demographic information of farmers. Was put as the determining factor the type of conventional and organic farming, and periods of drought and rainy. 56 volunteers were analyzed. The analyses were performed in the automatic biochemical Analyzer Cobas Integra 400 plus®. According to the results of the analyses, it was the largest number of individuals with reduced values of cholinesterase, specifically the Group of conventional farming, the period of greatest change index was in the rainy season, where the activity of AChE, expressive values presented in the city of São Sebastião, with 80% result of intoxicated, in the city of the foot – take, 21.73% over the same period. On analysis of the AChP, São Sebastião has obtained the highest number of contaminated with 18.75% and 30% respectively, in the District Take Foot stood between 10 and 21.73% of reduced levels of cholinesterase. This sets the organic system of cultivation, as the best alternative for prevention of future diseases, in addition to bringing quality of life for rural workers, as well as for consumers.
