Abstract

This study aimed to assess water quality based on physicochemical and microbiological parameters, identify the dominant social factors influencing pollution, and evaluate the performance of a Constructed Wetlands (CW) model as a domestic wastewater treatment solution. Water sampling was conducted at three stations along the Aur River in accordance with Indonesian National Standards (SNI). Dominant factor analysis was performed using linear and logistic regression with SPSS version 24, while CW performance was evaluated using independent t-tests in horizontal and vertical flow systems planted with three types of vegetation: water spinach, water hyacinth, and water lily. The results showed that the highest total coliform concentration was recorded at the downstream station, reaching 9 × 10⁶ MPN/100 mL. Septic tank ownership was identified as the most dominant variable associated with total coliform concentration (OR = 9.470). All water quality parameters decreased significantly after CW intervention (p = 0.000), with removal efficiencies of 91.43% for BOD, 86.41% for COD, 94.24% for ammonia, and up to 96.05% for total coliform. No significant difference in treatment performance was observed between the horizontal and vertical configurations, indicating that CW design selection may be guided by cost considerations and site-specific field conditions.

Abstract

Human breast milk is the best source of nutrition and immune protection for infants; however, various environmental contaminants such as pesticides, persistent organic pollutants (POPs), heavy metals, and emerging substances like microplastics have been detected in breast milk worldwide. In Indonesia, exposure risks may be higher in agricultural and industrial areas, potentially affecting milk quality and infant health. This narrative review aims to summarize scientific evidence on environmental contaminants in human breast milk and their possible health effects on infants in Indonesia. Relevant literature published between 2015 and 2025 was collected from PubMed, Scopus, Google Scholar, and national databases, including Garuda and SINTA. The reviewed studies reported the presence of organochlorine pesticides (notably p,p′-DDE), POPs such as PCBs and HCH, heavy metals, and microplastics in breast milk samples. Risk factors included pesticide use, environmental pollution, maternal body fat, and occupational exposure. Potential health impacts on infants involve neurodevelopmental disturbances, endocrine effects, and immune modulation. Nevertheless, evidence consistently shows that the benefits of breastfeeding outweigh the risks of low-level contaminant exposure. In conclusion, environmental contamination of breast milk is a public health issue that remains insufficiently monitored in Indonesia, highlighting the need for improved environmental surveillance, biomonitoring, and integrated policies while continuing to promote breastfeeding.
