“…Luo et al [ 17 ] surveyed a total 1,379 children in three areas near lead and zinc mining sites in China (2017), and found that the median blood lead concentration was 6.6 µg/dL, and that 341 children (24.73%) showed blood lead concentrations higher than 10 µg/dL, and that blood lead concentrations decreased as the age of children increased. A study conducted in Zambia (2015) showed an inverse correlation between the distance from lead and zinc mining sites and the blood lead concentration in children [ 18 ], and a study conducted in Vietnam (2018) showed an inverse correlation between the lead concentration in the soil, groundwater, and house dust, and the distance from sources of contamination [ 19 ]. On the other hand, in this study, no difference in lead concentration in children's blood was observed according to the distance of residence from the mine.…”

Background We evaluated the level and factors of heavy metal exposure to children residing in the Togttsetsii, Khanbogd, and Bayandalai soums of South Gobi province, Mongolia. Methods A total of 118 children aged 9–12 years were surveyed, and the level of heavy metal exposure in their bodies was investigated. Exposure was investigated by measuring concentrations of heavy metals such as cadmium, lead, and mercury in the blood; mercury concentration in the hair; and total arsenic in the urine. Results Blood cadmium concentration had geometric averages of 0.16 µg/L in the children from Bayandalai, 0.15 µg/L Tsogttsetsii, and 0.16 µg/L Khanbogd. Blood lead concentration showed a relatively higher geometric average of 7.42 µg/dL in the children from Bayandalai compared to 4.78 µg/dL and 5.15 µg/dL in those from Tsogttsetsii and Khanbogd, respectively. While blood mercury concentration was the highest in the children from Bayandalai, with a value of 0.38 µg/L, those from Tsogttsetsii and Khanbogd had similar concentrations of 0.29 µg/L and 0.29 µg/L, respectively. Hair mercury concentration was the highest in the children from Bayandalai, with a value of 78 µg/g, a particularly significant difference, with a concentration of 0.50 µg/g in those from Khanbogd. Urine arsenic concentration was the highest in the children from Khanbogd, with a value of 36.93 µg/L; it was 26.11 µg/L in those from Bayandalai and 23.89 µg/L in those from Tsogttsetsii. Conclusions The high blood lead concentration of children in Bayandalai was judged to be due to other factors in addition to mine exposure; the reason why blood and hair mercury concentration was higher in children from Bayandalai may have been due to exposure to many small-scale gold mines in the area. In the case of Khanbogd, it was estimated that the high arsenic level in urine was caused by the effect of mines.

“…Emisi industri juga merupakan sumber penting kontaminasi timbal pada tanah dan udara sekitar (Liang & Ghaffari, 2014). Timbal dari udara atmosfer atau cat terkelupas yang disimpan di tanah dan debu dapat dicerna oleh anak-anak dan secara substansial dapat meningkatkan kadar timbal darah mereka (Hai et al, 2018). Selain itu, makanan dan air juga bisa menjadi media penting untuk paparan awal terhadap timbal (Brown & Margolis, 2012).…”

Timbal merupakan logam yang bersifat toksik apabila terakumulasi di dalam tubuh dalam jumlah tertentu. Timbal masuk ke dalam sirkulasi darah dan beresiko menyebabkan kerusakan hati dimana dapat dilihat dengan pemeriksaan SGOT dan SGPT. Pada kondisi stres oksidatif dapat mengakibatkan terjadinya kerusakan sel hati sehingga tubuh memerlukan antioksidan eksogen, yang bisa didapatkan dari ekstrak kulit jeruk pacitan. Tujuan penelitian adalah untuk mengetahui pengaruh pemberian Ekstrak kulit jeruk pacitan pada kadar SGOT dan SGPT Rattus norvegicus wistar yang diinduksi dengan menggunakan timbal asetat. Metode penelitian ini adalah quasi experimental dengan rancangan post test only control group design. Sampel dibagi menjadi 5 kelompok yaitu Kelompok (G1) Rattus norvegicus diberi ransum pakan standar dan aquadest; (G2) diberikan Pb asetat peroral 30 mg/kgBB/hari, (G3) diberikan Pb asetat peroral 30 mg/kgBB/hari dan ekstrak kulit jeruk pacitan dosis 100 mg/kgBB/hari; (G4) diberikan Pb asetat peroral 30 mg/kgBB/hari dan ekstrak kulit jeruk pacitan dosis 200 mg/kgBB/hari; (G5) diberikan 30 mg/kgBB/hari dan ekstrak kulit jeruk pacitan dosis 300 mg/kgBB/hari. Penelitian telah mendapatkan surat keterangan layak etik No.EA/KEPK-Poltekkes_Sby/V/2022. Hasil penelitian berupa besar prosentase penurunan kadar SGOT dari kelompok G2 dengan kelompok perlakuan G3, G4 dan G5 yaitu 16%, 33%, dan 57%. Sedangkan untuk hasil penurunan kadar SGPT dari kelompok G2 dengan kelompok perlakuan G3, G4 dan G5 yaitu 25%, 34%, 46%. Kesimpulan ekstrak kulit jeruk pacitan memberikan pengaruh yang signifikan terhadap kadar SGOT dan SGPT pada Rattus norvegicus yang diinduksi PbCH3COO dengan nilai signifikasi < 0,005.

“…As a result of EPA's regulatory efforts including the removal of Pb from motor vehicle gasoline, levels of Pb in the air decreased by 98% between 1980 and 2014 (Hai et al 2018). Still high level of Pb pollution is an important issue in Lucknow.…”

The present work aims to investigate seasonal variations in air pollution levels in Lucknow and assess the ambient air quality of the city together with highlighting the health impacts of major pollutants like PM 10 , PM 2.5 , SO 2 , NO 2 , Pb, Ni and aerosols from 2010 to 2019. The maximum and minimum values of PM 10 , PM 2.5 , SO 2 , NO 2 , Pb and Ni were found to be 270.75 and 122.45 μg/m 3 , 124.95 and 95.52 μg/m 3 , 25.60 and 8.05 μg/m 3 , 75.65 and 23.85 μg/m 3 , 0.66 and 0.03 μg/m 3 and 0.07 and 0.01 ng/m 3 , respectively. Health impact of particulate matter has also been assessed with AirQ+, and it was estimated that long-term exposure of PM 10 was attributed to between 37 and 48% for post-neonatal (age 1–12 months) mortality rate due to all causes, whereas long-term attributable proportions in mortality due to exposure of PM 2.5 were to about 19 to 28% from all causes. Further, an attempt has also been made to evaluate the impact of lockdown amid COVID-19 on the ambient air quality of Lucknow. During the lockdown, PM 2.5 levels reduced by 65% (at Gomti Nagar), 23% (at central school), 79% (at Lalbagh) and 35% (at Talkatora), due to which, air quality index of Gomti Nagar came down to 43, well below 50 which falls in the healthy range. NO 2 levels also came down. However, levels of SO 2 did not show significant reduction. Correlating the data between aerosol optical depth and Angstrom exponent by Pearson correlation analysis revealed a significant positive correlation ( r = 0.65, P < 0.001).
