The use of zebrafish (Danio rerio) has arisen as a promising biological platform for toxicity testing of pesticides such as herbicides, insecticides, and fungicides. Therefore, it is relevant to assess the use of zebrafish in models of exposure to investigate the diversity of pesticide-associated toxicity endpoints which have been reported. Thus, this review aimed to assess the recent literature on the use of zebrafish in pesticide toxicity studies to capture data on the types of pesticide used, classes of pesticides, and zebrafish life stages associated with toxicity endpoints and phenotypic observations. A total of 352 articles published between September 2012 and May 2019 were curated. The results show an increased trend in the use of zebrafish for testing the toxicity of pesticides, with a great diversity of pesticides (203) and chemical classes (58) with different applications (41) being used. Furthermore, experimental outcomes could be clustered in 13 toxicity endpoints, mainly developmental toxicity, oxidative stress, and neurotoxicity. Organophosphorus, pyrethroid, azole, and triazine were the most studied classes of pesticides and associated with various toxicity endpoints. Studies frequently opted for early life stages (embryos and larvae). Although there is an evident lack of standardization of nomenclatures and phenotypic alterations, the information gathered here highlights associations between (classes of) pesticides and endpoints, which can be used to relate mechanisms of action specific to certain classes of chemicals. 相似文献

The increasing concern regarding the preservation of soil quality suggests the adoption of quality reference values as a first step in environmental monitoring actions. In this context, the objective of this study was to establish soil quality reference values for Al, Zn, Mn, Cd, Fe, Pb, Ni, Cr, and Cu and to correlate several soil properties with the occurrence of these elements in the hillslope region of Rio de Janeiro State. Sixty-two samples were collected at depths of 0–20 and 20–40 cm and analyzed using the USEPA method 3051A. After clustering analysis, the samples were separated into three groups. Classification functions were obtained based on the variables pH - Mg - Fe - Mn, i.e., the variables that were best related to heavy metal content. We determined to establish the quality reference values for the 75th percentile of the three groups. The relief forms of the area, which facilitate the transport of soil fine-particle fractions and accumulation in lowlands, were revealed to be one of most important factors in understanding the distribution of soil heavy metals. 相似文献

Fences are very common in rural areas, and represent important landscape elements in both tropical and temperate climate regions.
In spite of their marked presence and importance, fences have been little studied, principally in Brazil. The present study
examined the types of fences, the diversity of species used in their construction, as well as the diversity of their uses
in a rural community in the municipality of Caruaru, Pernambuco State, northeastern Brazil. Fifty meters of fence-line in
each of 50 rural properties in the community were examined, noting the diameter, height and identity of all vegetation elements
used in their composition. Semi-structured interviews were also held with their builders in order to obtain information concerning
fence uses. In the total of 2,500 linear meters of fence-line, 4,953 individual plant elements were identified, belonging
to 51 different species. A majority of the fence elements were non-living fence posts, although the number of living posts
was high. Of the total number of fence elements, 66.7% were native to the caatinga region. The large number of native species used as non-living fence posts indicates an intensive use of the caatinga vegetation and suggests the need to stimulate the use of living fence posts for conservation purposes. 相似文献

Banana fibers, as well as other lignocellulosic fibers, are constituted of cellulose, hemicellulose, lignin, pectin, wax and
water soluble components. The abundance of this fiber combined with the ease of its processing is an attractive feature, which
makes it a valuable substitute for synthetic fibers that are potentially toxic. In this work, the structure characterization
of the banana fiber modified by alkaline treatment was studied. Some important properties of this fiber changed due to some
chemical treatments, such as the crystalline fraction, dielectric behavior, metal removal (governed by solution pH) and biodegradation.
Our results showed that treated banana fiber is a low cost alternative for metal removal in aqueous industry effluents. Thus,
for regions with low resources, the biosorbents are an alternative to diminish the impact of pollution caused by local industries,
besides being a biodegradable product. 相似文献
