2026-09-18 XDA28100503—Target Dataset for Dynamic Monitoring of Water Environment and Crop Water, Fertilizer, and Pesticide Use in Irrigation Districts of the Sanjiang Plain, China (2022) doi:10.57760/sciencedb.iga.01100 en This dataset focuses on the farmland ecosystem of the irrigation districts in the Sanjiang Plain, China, and systematically integrates three sub‑datasets: #1 Basic Water Quality Parameter Dataset of Irrigation District Water Environment, #2 Physicochemical and Toxicity Dataset of Multi‑Media Organic Pollutants in Irrigation Districts, and #3 Monitoring Dataset of Multi‑Media Organic Pollutants in Irrigation Districts. Sub‑dataset #1 includes five core indicators—pH, temperature (℃), oxidation‑reduction potential (mV), electrical conductivity (μs/cm), and dissolved oxygen (mg/L)—which characterize the basic physicochemical properties of water bodies. Sub‑dataset #2 contains nine physicochemical properties such as water solubility, logarithm of the n‑octanol/water partition coefficient (log Kow), and logarithm of the organic carbon adsorption coefficient (log Koc), as well as toxicity data for three types of organisms including fish, daphnia, and green algae. Sub‑dataset #3 presents monitoring results for 444 organic chemicals, including parameters such as one‑dimensional retention time, two‑dimensional retention time, CAS number, and Chinese and English names, along with compound detection data from different sampling sites. All data are uniformly stored in Excel (.xlsx) format. Spatially, the dataset covers three major regions in the core irrigation districts of the Sanjiang Plain—Erdaohe Farm, Youyi Farm, and Xingkaihu Farm—and includes multiple water types such as irrigation water, farmland water, drainage water, and surface water. Temporally, it spans April to September 2022, fully covering the three key crop growth stages: sowing, growing, and maturity. In terms of media, the dataset includes four types of monitored matrices—water, suspended particulate matter, soil, and crops—enabling comprehensive multi‑media monitoring. The dataset comprises a total of 693 valid records, including 59 water environment basic parameter records, 534 physicochemical and toxicity records of organic pollutants, and 100 pollutant monitoring records.
