Artikel Review : Efek Pencemaran Air Jangka Panjang Di Sungai Yangtze, China
AI summary Read the abstract
Researchers reviewed long-term water pollution in China's Yangtze River through a literature analysis, documenting contamination from heavy metals (Pb, As, Cr, Zn, Ni), microplastics, and industrial and agricultural runoff, with lead showing the highest pollution index and Nanhui East Shoal recording the highest concentrations.
Sungai Yangtze merupakan sungai terbesar ketiga di dunia yang kini telah tercemar oleh bahan-bahan pencemar seperti logam berat, mikroplastik dan lain sebagainya. Pencemaran ini diduga terjadi karena adanya aktivitas-aktivitas industri, pertanian, dan permukiman yang mana limbahnya tidak dikelola dengan semestinya sehingga limbahnya menimbulkan dampak yang sangat luas. Adapun tujuan dari artikel review ini adalah untuk mengetahui jenis pencemaran apa saja yang ada di sungai Yangtze beserta efek yang ditimbulkan, baik untuk lingkungan maupun kesehatan makhluk hidup. Penelitian ini dilakukan dengan menggunakan metode literature review, dimana literature yang digunakan merupakan literature yang bersangkutan dengan pencemaran air yang ada di sungai Yangtze, China. Pencarian literatur review ini dilakukan dengan empat prosedur, yaitu identifikasi, skrining, kelayakan dan keterimaan. Hasil yang didapatkan kemudian dijelaskan secara deskriptif dan akan dijabarkan dalam bentuk gambar. Hasil dari artikel review ini menunjukkan bahwa Shoal Nanhui Timur memiliki tingkat pencemaran Pb tertinggi, yaitu sebanyak 768, diikuti oleh beberapa lokasi lain seperti Pantai Yuanyuansha sebanyak 716 dan bagian bawah saluran Selatan sebanyak 692. Selain Pb, pencemaran seperti As, Cr, Pb, Zn, dan Ni juga terdapat di Kawasan sungai Yangtze, China. Sehubungan dengan rata-rata simpangan baku berlebih, tingkat pencemarannya adalah Pb (8,34) > Cu (0,57) > Cr (0,37) > Zn (0,355) > Ni (0,352) > As (0,28) > Cd (0,00).

From Legacy Contamination to Green Infrastructure: Heavy Metal, Microplastics and Nutrient Pollution Management in the Yangtze River Basin
AI summary Read the abstract
This review pulls together 30 years of research on China's Yangtze River, finding that while cleanup efforts have cut heavy metal pollution by over a third since 2013, real risks remain — including rice grown in the region still testing above safe cadmium limits and groundwater with unsafe arsenic levels, plus a staggering 8.3 trillion microplastic particles flowing into the sea each year. Since this river basin is home to over 400 million people who rely on it for food and water, these findings matter globally as a case study for how industrial pollution can persist for decades even after regulations improve, and why continued monitoring of contaminants in our food
Extent and risks of microplastic pollution in the Yangtze River. State of the science
AI summary Read the abstract
This review analyzed data from 21 studies on microplastic pollution in the Yangtze River, one of the most polluted rivers in the world. Researchers found that many existing studies had quality issues that make it difficult to accurately assess the true risks. The study calls for higher-quality, standardized research methods to properly evaluate how microplastics are affecting one of Asia's most important waterways.

AI summary Read the abstract
A comprehensive survey of the Yangtze River basin — the longest river in China — found microplastics at abundances ranging from 21 to over 44,000 particles per cubic meter, with the highest concentrations in urban tributary areas like Chengdu. Fibers and fragments under 1 mm were most common, and statistical analysis linked microplastic abundance strongly to vehicle ownership and tourism activity. The study found that roughly 69% of sampled areas fall within elevated ecological risk categories, with Taihu Lake identified as a particular hotspot.
