Study finds farm chemicals killing more bees 混合殺蟲劑增加蜜蜂死亡數(shù)量
根據(jù)對 90 項(xiàng)研究進(jìn)行的分析， 那些預(yù)先混合好然后賣給農(nóng)民的農(nóng)藥會(huì)殺死兩倍數(shù)量的蜜蜂。
Our bees face multiple threats to their survival – from a loss of food rich natural grassland to the dozens of chemical pesticides that are commonly used in agriculture.
我們的蜜蜂面臨多種生存威脅——從失去孕育著豐富食物資源的天然草場，到農(nóng)業(yè)中常用的幾十種化學(xué)殺蟲劑。
This study set out to measure how those different stresses interact to affect the insects. The researchers examined 90 studies that each measured the effect on bee health of a specific agricultural chemical or another environmental challenge.
這項(xiàng)研究衡量了這些不同的壓力是如何相互作用并影響這種昆蟲的。研究人員檢查了90項(xiàng)研究，其中每一項(xiàng)都衡量了一種特定農(nóng)藥或另一種環(huán)境挑戰(zhàn)對蜜蜂健康造成的影響。
They worked out that combinations of several chemicals killed many more bees than expected. This is because, the researchers say, pesticides interact.
他們發(fā)現(xiàn)，幾種化學(xué)物質(zhì)的組合所殺死的蜜蜂比預(yù)期的要多得多。研究人員表示，這是因?yàn)闅⑾x劑會(huì)相互作用。
Each chemical enhances the damage caused by another. Since pesticides are often sold as mixtures of compounds to use on crops, the scientists say that the regulation of these chemicals needs to be updated to factor in this harmful interaction, and to protect our threatened and precious pollinators.
每種化學(xué)物質(zhì)都會(huì)增強(qiáng)另一種化學(xué)物質(zhì)造成的傷害。由于用于農(nóng)作物的殺蟲劑常以化學(xué)混合物的形式出售，科學(xué)家指出，需要更新對這些化學(xué)物質(zhì)的監(jiān)管條例，將這種有害的相互作用納入考慮因素，從而保護(hù)這些受到威脅的珍貴傳粉昆蟲。

答案
1. What threats do bees face?
They face multiple threats to their survival – from a loss of food rich natural grassland to the dozens of chemical pesticides that are commonly used in farming.
2. What did the 90 studies that the researchers examined measure?
The 90 studies each measured the effect of a specific agricultural chemical or another environmental challenge on the health of bees.
3. What did the scientists work out from the study?
They worked out that combinations of several chemicals killed many more bees than expected.
4. What do the scientists believe needs to be updated?
They say the regulation of these chemicals needs to be updated.
