<p>地表水采樣的注意事項：</p><p>1.采樣時不可攪動水底部的沉積物。</p><p>2.采樣時應保證采樣點的位置準確。</p><p>3.認真填寫水質采樣記錄表</p><p>4.保證采樣按時，準確，安全。</p><p>5.采樣結束前，應核對采樣計劃，記錄與水樣，如有錯誤或遺漏，應立即補采貨重采。</p><p>6.如采樣現場水質均勻，無法采到有代表性樣品，則應詳細的記錄不均勻的情況和試劑采樣情況，提供使用數據者參考，并將此現場情況向環境保護行政主管部門反映。</p><p>7.測定油類樣品，應再睡眠至水下300mm采集柱狀水樣，單獨采樣，全部用于測定。采樣瓶（容器）不能用采集的水樣沖洗。</p><p>8.測定溶解氧，生化需氧量和有機污染物等項目的水樣時，必須注滿容器，不留空間，并用水封口。</p><p>9.如果水樣中含有沉降性固體（如泥沙等）應用分離除去。</p><p>10.測COD，高猛酸鹽指數，葉綠素a，總氮，總磷水樣，靜置30分鐘后，用吸管一次或者幾次移取水樣，吸管進水尖嘴應插至水樣表層50mm以下位置，再加入保存劑保存。</p><p>11.測油類，BOD5.DO、硫化物，余氯，糞大腸菌類，懸浮物，放射性等項目要單獨采樣。</p><p>更多相關，請青島尚德環保科技有限公司。</p>
