“…Jalur utama paparan timbal pada anak dapat ditunjukkan dengan identifikasi jalur paparan timbal. Penelanan masih merupakan jalur paparan timbal yang dominan baik untuk anak-anak, tetapi partikel dan debu dari pembakaran batu bara dan cat bertimbal dari renovasi rumah tidak dapat diabaikan (Chen et al, 2023) Chen ( 2023) juga mengeksplorasi hubungan langsung antara timbal dalam darah anak-anak dengan sumber pencemaran lingkungan di area pembakaran batu bara, membuktikan bahwa mereka semua terpapar timbal dari sumber yang sama, yaitu pembakaran batu bara. Berdasarkan karakteristik isotop dari media lingkungan dan batu bara yang berbeda, penelitian ini lebih jauh mengklarifikasi bahwa anak-anak terutama terpapar timbal yang dilepaskan dari pembakaran batu bara terutama melalui konsumsi makanan, inhalasi bahan partikulat dan debu, inhalasi dan kontak kulit.…”

“…Dengan jalur dan sumber paparan timbal yang serupa maka berspekulasi bahwa media lingkungan utama dan sumber paparan timbal pada anak-anak dapat diindikasikan berdasarkan jalur paparan timbal dan sumber kontaminasi dengan berbagi lingkungan hidup yang sama. (Chen et al, 2023). Penelitian sejalan oleh Chai (2020) bahwasannya kondisi polusi timbal di dekat area tambang timbal-seng sangat serius, dan paparan timbal secara signifikan mempengaruhi TSH serum, kadar GABA, dan kinerja IQ anak usia sekolah (Cai et al, 2021) Penelitian di negara China juga ditemukan sejalan dengan penelitian yakni ditemukannya kadar timbal darah (BLL) rata-rata anak-anak adalah 84,8 μg/L.…”

Lead is a toxic and pervasive metal. Chronic exposure to low levels is responsible for significant health effects, particularly in early adolescent. Prevention remains the best option for reducing lead exposure. The objective of the present study was to determine the association between knowledge and consumption of vitamin c with lead exposure in early adolescents’ urine. This research is a quantitative study with cross sectional study design. Research subjects were 52 adolescents aged 12-16 years from Kadu Village, Curug. We examined associations of levels of knowledge and consumption of vitamin c with urine lead levels (Pb-U). We used a brief questionnaire on prevention for lead poisoning, included to measure knowledge (from Chicago Lead Knowledge Test Questionnaire) and daily intake of vitamin C (from Food Frequency Questionnaire) completed by respondents. Pb-U was measured using ICP-OES. The average urine lead levels of the early adolescents was 28,88 μg/L (median: 27,70 μg/L; CI 95% 24,85-32,90) (n=52), and Std. 14,46 μg/L. There was a significant difference between knowledge and the levels of Pb in the urine of early adolescent (p = 0,045). There was no significant difference between the consumption of vitamin c and the levels of Pb in the urine of early adolescent (p = 0,379). The hypothesis proved that the levels of knowledge affects lead levels in the urine of early adolescents. Therefore, it is suggested that government should educate the public about lead and its preventive actions and collaborate with policy makers to be more efficient.

“…Lead exposure has two main sources: food intake and coal combustion, with the latter being a significant source of lead exposure for children and domestic dogs (38). A recent study conducted in Australia demonstrated that during seasonal deer hunting, dogs are more exposed to heavy metals due to their consumption of game meat instead of common industrial feed (39).…”

IntroductionDogs are human companions and share environmental conditions with their owners. Epidemiological studies have shown that dogs seem to be good sentinel animals for the association of diseases and/or mortality provoked by chronic exposure to heavy metals (Cd, Pb).MethodsIn the present work, we analyze the registered death cases and population from the National Canine Registry from 2020 to 2022, involving a dog population of 582,564 and 17,507 deaths. The mortality rate in male and not-purebred dogs is higher than in female and purebred dogs, respectively. The mortality cases were cross-referenced with the environmental pollution data relating to the concentration of Cd and Pb detected, between 2012 and 2022, in the various municipalities of the Liguria region. We then calculated SMR (Standardized Mortality Rate) throughout the region and found that mortality increases from the eastern to the western Ligurian coast.Results and discussionWe observed that the most polluted areas present the highest SMRs (IRR = 1.36, 95%CI: from 1.31 to 1.41). Considering dog ages, we found that mortality in young dogs is not affected by pollution, while mortality in old dogs (10–20 years old) is heavily affected by it (IRR = 8.97, 95%CI from 8.09 to 9.93). In conclusion, the data suggest the importance of canine health and biomonitor studies and provide a basis for future research involving both animal and human health.
