Resumo
Os POPs são substâncias químicas orgânicas sintéticas e apresentam características físicas e químicas, tais como: semivolatiliddade, persisitência, bioacumulação e toxicidade, diferenciando em si de outras substâncias químicas, o objetivo deste trabalho foi avaliar a presença de poluentes orgânicos persistentes (POPS) em artigos infantis e seu impacto na saúde humana na Região Metropolitana de Sorocaba, São Paulo – SP, foram coletadas 120 amostras de artigos infantis, tais como: bico de chupeta usado, bico de mamadeiras usados, bico de copinho usado, copo de mamadeira usado, disco de chupeta usado, mordedor usado, espuma de bebê conforto, tecido de bebê conforto, e após foram realizadas extrações com diclorometano para as quantificações de PBDEs. (BDE-28, -47, -99, -100, -153, -154, -183 e -209) por cromatografia gasosa e detecção por espectrometria de massas (CG/MS). Os resultados mostraram a presença de PBDEs em 4,16% (n=5), que excederam o Limite de Máximo de Concentração de Poluentes Orgânicos Persistentes (LPCL) maiores de 500 mg Kg-1 de PBDEs. O BDE-99 foi o mais abundante e o BDE-153 em menor concentração. Os POPs são muitos tóxicos aos seres humanos, podendo desencadear efeitos nocivos agudos ou crônicos, sendo que o maior risco de exposição a fontes de contaminação é com lactentes com idade entre 3 e 18 meses, devido diferenciações no seu peso corporal e capacidade de metabolismo celular. Das 14 amostras analisadas de bico de chupeta usado e 15 amostras de bico de mamadeira usado, ultrapassaram o limite máximo permitido de ingestão diária de BDE-209 (0,007 mg/Kg), predominando a faixa etária de 03-06 meses, respectivamente a faixa etária 6-12 meses, faixa etária de 12-24 meses e a faixa etária de 24-36 meses.
POPs are synthetic organic chemical substances and have physical and chemical characteristics, such as: semi-volatility, persistence, bioaccumulation and toxicity, differentiating themselves from other chemical substances. The objective of this work was to evaluate the presence of persistent organic pollutants (POPS) in articles children and their impact on human health in the Metropolitan Region of Sorocaba, São Paulo – SP, 120 samples of children's items were collected, such as: used pacifier nipples, used baby bottle nipples, used baby cup nipples, used baby bottle cups, disc of used pacifiers, used teethers, baby comfort foam, baby comfort tissue, and then extractions were carried out with dichloromethane to quantify PBDEs. (BDE-28, -47, -99, -100, -153, -154, -183 and -209) by gas chromatography and mass spectrometry (GC/MS) detection. The results showed the presence of PBDEs in 4.16% (n=5), which exceeded the Maximum Persistent Organic Pollutant Concentration Limit (LPCL) greater than 500 mg Kg-1 of PBDEs. BDE-99 was the most abundant and BDE-153 was in the lowest concentration. POPs are very toxic to humans and can trigger acute or chronic harmful effects, with the greatest risk of exposure to sources of contamination being in infants aged between 3 and 18 months, due to differences in their body weight and cellular metabolism capacity. . Of the 14 samples analyzed from used pacifier nipples and 15 samples from used bottle nipples, they exceeded the maximum permitted daily intake limit of BDE-209 (0.007 mg/kg), with a predominance of the age group of 03-06 months, respectively the age group 6-12 months, 12-24 months age group and 24-36 months age group.
