AI Article Synopsis
- The study investigated heavy metal levels in cow's milk from areas irrigated with wastewater and assessed the health risks for children's daily consumption.
- Results indicated that lead (Pb) levels exceeded Codex limits, while arsenic (As) posed significant health risks with values over 1 in the hazard quotient.
- The individual cancer risk was highest for arsenic (As), followed by cadmium (Cd), chromium (Cr), and lead (Pb), with a total risk highlighting serious concerns for both boys and girls.
Article Abstract
This study aimed to determine the heavy metal content in cow's milk produced in areas irrigated with waste water and to evaluate the health risk with daily consumption of milk for children. The sample consisted of four zones in which small farmers were selected and the milk of 160 cows in two seasons of the year. On average, the metals in the milk in decreasing order were 0.36; 0.046; 0.035; 0.029; 0.015; 0.012, and 0.002 mg kg for Zn, Pb, As, Cu, Cr, Ni, and Cd, respectively. The Pb exceeded the limits allowed by Codex. The values shown in the hazard quotient for the As of more than 1 and HI were higher. On the other hand, the individual risk of cancer showed a descending order As> Cd> Cr> Pb, while the total risk indicated that the combined effect of metals put girls and boys at serious risk.

REACH assessment of humans exposed to chemicals indirectly via the environment: screening modeling in EUSES versus state of the science.
Integr Environ Assess Manag

Henkel AG & Co KGaA, Düsseldorf, Germany.
The assessment of humans indirectly exposed to chemicals via the environment (HvE) is an assessment element of the Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) regulation. The European Union System for the Evaluation of Substances (EUSES) is the default screening tool, aimed at prioritizing chemicals for further refinement/higher tier assessment. This review summarizes the approach used in EUSES, evaluates the state of the science in human exposure modeling via the environment, and identifies areas for further research to strengthen the confidence and applicability of EUSES for assessing HvE.

Yingshan Fucheng Meat Pigeon Breeding Professional Cooperative, Nanchong, China.
Background: Pigeons are significant economic animals in China; however, research regarding the establishment and influencing factors of gut microbiota in squabs remains limited. Understanding how the gut microbiota develops in pigeons, particularly in relation to pigeon milk, is importance in pigeon production. This study aims to elucidate the establishment characteristics of the gut microbiota in White King pigeon squabs and explore the role of pigeon milk in this process.
