Assessment of the variation of heavy metals and pesticide residues in native and modern potato (Solanum tuberosum L.) cultivars grown at different altitudes in a typical mining region in Peru
(2023) [Artigo de periódico]This research paper presents the preliminary outcomes of an investigation conducted on the levels of heavy metals (such as As, Cd, Pb, Al, Mn, Cu, Ba, Cr, and Ni) and pesticide residues found in both traditional and modern ... -
Desenvolvimento de métodos analíticos para determinação de agrotóxicos em sedimentos por cromatografia gasosa monodimensional e bidimensional abrangente com micro detector de captura de elétrons
(2010) [Artigo de periódico]The development of analytical methods for determination of eight pesticides of different chemical classes (trichlorfon, propanil, fipronil, propiconazole, trifloxystrobin, permethrin, difenoconazole and azoxystrobin) in ... -
Investigation of potential biomarkers for the early diagnosis of cellular stability after the exposure of agricultural workers to pesticides
(2016) [Artigo de periódico]Agricultural workers involved in the harvest of tobacco crops are regularly exposed to large quantities of pesticides. In order to determine how this exposure to pesticides induces genetic alterations in these workers, ... -
Materiais SiO2-TiO2 para a degradação fotocatalítica de diuron
(2011) [Artigo de periódico]SiO2-TiO2 materials prepared by sol-gel method were evaluated in the photocatalytic degradation of diuron. The materials were prepared with and without surfactant cetyltrimethylammonium chloride at different temperatures ... -
Multiresidue determination of pesticides in carrots using pressurized liquid extraction and gas chromatography with mass spectrometry detector
(2010) [Artigo de periódico]Neste estudo, 14 agrotóxicos (captan, clorotalonil, deltametrina, dicloran, fention, folpete, iprodiona, linurom, malationa, prometrina, procloraz, procimidona, triclorfom e trifluralina) foram usados no desenvolvimento ... -
Sorção de atrazina e de mesotriona em latossolos e estimativa do potencial de contaminação
(2011) [Artigo de periódico]Following application herbicides usually reach the soil and undergo several dissipation processes which determine their effects on target organisms and on the environment. This work aimed to evaluate atrazine and mesotrione ...
