phosphorus；TP）飼料中以無機(jī)態(tài)和有機(jī)態(tài)存在的磷的總和。測定方法正磷酸鹽的常用測定方法有3種： ①釩鉬磷酸比色法。此法靈敏度較低，但干擾物質(zhì)較少。 ②鉬-銻-鈧比色法。靈敏度高，顏色穩(wěn)定，重復(fù)性好。 ③ 氯化亞錫法。雖靈敏但穩(wěn)定性差，受氯離子、***鹽等干擾。磷是畜禽飼料中的重要指標(biāo),畜禽對磷的攝入量不足或過量都將嚴(yán)重影響畜禽健康,因此飼料必須經(jīng)常檢測。根據(jù) GB/T6437 飼料中總磷的測定分光光度法采用釩鉬磷酸比色法的原理。</p><p style="text-indent:25px">隨著環(huán)境保護(hù)工作的日益重視與加強(qiáng)，如何消除磷污染問題正成為人們越來越關(guān)注的課題。一、磷污集的來源 (一)工業(yè)污水食品加工、發(fā)酵、洗滌劑生產(chǎn)等工廠的廢水中含有大量的磷。(二)生活污水生活污水中的磷主要來自含磷合成洗滌劑的大量使用。 (三)含磷的化肥與農(nóng)藥為了提高農(nóng)作物產(chǎn)量，在我國農(nóng)村磷肥與有機(jī)磷農(nóng)藥常常會被大量使用。二、磷的危害 (一)磷對人的危害 (1)對皮膚的危害：高磷洗衣粉對皮膚有直接刺激危害，會產(chǎn)生灼燒疼痛的感覺，洗后的衣物穿在身上有時又會造成皮膚瘙癢，高磷洗衣粉已成為接觸性皮炎、嬰兒尿布疹等常見皮膚病的刺激源。 (2)對神經(jīng)中樞的危害：人體內(nèi)有一種重要的神經(jīng)傳導(dǎo)物質(zhì)已酰膽堿酯酶，有機(jī)磷會抑制膽堿酯酶使其無法分解已酰膽堿酯酶，造成神經(jīng)中樞蓄積大量乙酰膽堿酯酶，從而引起中毒.嚴(yán)重者甚至可能引起死亡。 (3)長期低劑量的有機(jī)磷農(nóng)藥不僅可使人慢性中毒并可能對人體產(chǎn)生致*、致畸等危害。 (二)磷對海洋生物的危害海洋生物大多對有機(jī)磷農(nóng)藥十分敏感，一些耐***昆蟲毫無反應(yīng)的農(nóng)藥濃度，很快能夠使海洋生物致死。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
