ABSTRACT
The aim of this study is to determine the association between environmental organic pollutants with type 2 diabetes. This prospective study was conducted in Federal Urdu University of Arts, Science and Technology (FUUAST) Gulshan-e-Iqbal Campus Karachi in duration from January 2016 to June 2017. This study was ethically approved from the Institutional Review Board of FUUAST. The study included 50 male and female convenient subjects with type 2 diabetes. Subject with other type of diabetes was excluded. Consent was obtained by each individual. Self-structured questionnaire was used for data collection. The comparative results suggest that the maximum level of summation polychlorinated biphenyls (PCBs) mean value was found in age group 27-33 as 0.695 mg/kg in 73% having total individual eleven. Median (interquartile range) of pesticides levels among subjects with normal weight, over weight and obesity were 0.49 (0.26-2.13), 1.53 (0.60-2.65), and 1.60 (1.23-2.05) respectively. It was observed that Organochlorine pesticides (OCS) levels of subjects with overweight and obesity were almost similar (P-value > 0.05) but significantly higher as compared to subjects with normal weight (P-value < 0.05). No significant differences were observed between PCB levels of subjects in terms of body mass index (BMI). In present study we trace the important elements involve in the deposition of persistent organic pollutants and established an association between pollutants with etiology of diabetes and associated disorders such as obesity.
O objetivo deste estudo é determinar a associação entre poluentes orgânicos ambientais com diabetes tipo 2. Este estudo prospectivo foi conduzido na Universidade Federal Urdu de Artes, Ciência e Tecnologia (FUUAST), Gulshan-e-Iqbal, Campus Karachi, com duração de janeiro de 2016 a junho de 2017. Este estudo foi eticamente aprovado pelo Comitê de Revisão Institucional da FUUAST. O estudo incluiu 50 indivíduos convenientes do sexo masculino e feminino com diabetes tipo 2. Indivíduos com outro tipo de diabetes foram excluídos. O consentimento foi obtido por cada indivíduo. Um questionário autoestruturado foi utilizado para a coleta de dados. Os resultados comparativos sugerem que o nível máximo de soma de bifenilas policloradas (PCBs) valor médio foi encontrado na faixa etária 27-33 como 0,695 mg / kg em 73%, tendo total de 11 indivíduos. A mediana (intervalo interquartil) dos níveis de pesticidas entre indivíduos com peso normal, sobrepeso e obesidade foi de 0.49 (0.26-2.13), 1.53 (0.60-2.65) e 1.60 (1.23-2.05), respectivamente. Observou-se que os níveis de pesticidas organoclorados (OCS) de indivíduos com sobrepeso e obesidade eram quase semelhantes (valor P > 0.05), mas significativamente maiores em comparação com indivíduos com peso normal (valor P < 0.05). Não foram observadas diferenças significativas entre os níveis de PCB dos indivíduos em termos de índice de massa corporal (IMC). No presente estudo, rastreamos os elementos importantes envolvidos na deposição de poluentes orgânicos persistentes e estabelecemos uma associação entre os poluentes com a etiologia do diabetes e doenças associadas, como a obesidade.

The present study was conducted to measured heavy metals in cyprinid fishes in rivers of District Khuzdar Balochistan, Pakistan. In the present study, 25 fish samples were collected that belonged to 8 order of 13 families, The Cyprinidae family had the largest number of eight fish species. Present study is focused on Heavy metals in cyprinid fishes. Heavy metals accumulation like Zinc, Manganese, Copper, and Nickel was evaluated in water and various organs of fishes. Atomic Absorption Spectroscopy was used for the identification of these heavy metals in fish species and water bodies. The average concentration (mg/L) of Zn 0.26-0.41, Mn 0.030- 0.073, Cu 0.017—0.080 and NI 0.14-0.79 were observed in water. The Concentration (mg/L), of Zn Conc 0.383-.028 Mn Conc .073- .030 Cu Conc 080-.017 NI Conc .79-.14. The concentration of heavy metals was found both similar and varied simultaneously across the whole research area. Zinc concentration was reported highest, whereas Copper was at the lowest concentration in all fish species .The concentration of heavy metals, in all the fish species under this study, was above the threshold of WHO limits.
O presente estudo foi realizado para medir metais pesados em peixes ciprinídeos em rios do Distrito Khuzdar Balochistan, Paquistão. No presente estudo, foram coletadas 25 amostras de peixes pertencentes a 8 ordens de 13 famílias. A família Cyprinidae apresentou o maior número de oito espécies de peixes. O presente estudo está focado em metais pesados em peixes ciprinídeos. O acúmulo de metais pesados como zinco, manganês, cobre e níquel foi avaliado na água e em vários órgãos dos peixes. A Espectroscopia de Absorção Atômica foi utilizada para a identificação desses metais pesados em espécies de peixes e corpos d'água. A concentração em água ((mg/L),) Zn Conc. 0,383-.028 Mn Conc. .073- .030 Cu Conc. 080-.017 NI Conc. 0,79-.14. A concentração de metais pesados foi considerada semelhante e variou simultaneamente em toda a área de pesquisa. A concentração de zinco foi relatada mais alta, enquanto o cobre estava na concentração mais baixa em todas as espécies de peixes. A concentração de metais pesados, em todas as espécies de peixes neste estudo, estava acima do limite dos limites da Organização Mundial da Saúde (OMS).
