style="font-size:12.0pt;">近段時間，想必大家最關注的莫過于新冠狀病毒的流行。而與每個人息息相關的，莫過于新冠病毒的傳染途徑；其中，所謂的“氣溶膠傳播”更是重中之重。在了解氣溶膠傳播之前，我們有必要先認識一下氣溶膠是什么？</span></span></p> <p align="left" style="text-align:left;line-height:150%;"> </p> <p align="left" style="text-align:left;line-height:150%;"> <strong><span style="font-family:宋體;"><span style="font-size:12.0pt;">氣溶膠與顆粒物的關系</span></span></strong></p> <p align="left" style="text-align:left;text-indent:24.0pt;line-height:150%;"> <span style="font-family:宋體;"><span style="font-size:12.0pt;">作為國內首批大氣顆粒物監測企業之一，四川瞭望對“氣溶膠”并不陌生。所謂的氣溶膠指的是懸浮在空氣中的固定及液體顆粒，大多數粒徑在0.01~10</span>微米之間，由自然及人為因素產生。</span></p> <p align="left" style="text-align:left;text-indent:24.0pt;line-height:150%;"> <span style="font-family:宋體;"><span style="font-size:12.0pt;">而絕大部分氣溶膠的粒徑大小都小于10</span>微米，屬于可吸入顆粒物PM10</span>；當人呼吸時，這些顆粒物可以直接達到人體支氣管和肺泡。四川瞭望在全國各地的各類在線儀器大多都可以對這類顆粒物實施連續濃度監測，僅在成都地區就擁有數千套設備可在線監測PM10濃度。</p> <p align="left" style="text-align:left;text-indent:24.0pt;line-height:150%;"> <span style="font-family:宋體;"><span style="font-size:12.0pt;">而氣溶膠中，粒徑小于等于2.5</span>微米的，便屬于大名鼎鼎的PM2.5</span>了。由于PM2.5體積更小，所以其擁有更強的穿透力，可以直達人體支氣細壁，干擾肺部的氣體交換。根據當前公布的新冠病毒信息，可以初步認為，主要就是吸附在PM2.5顆粒上新冠病毒會進行氣溶膠傳播。</p> <p align="left" style="text-align:left;line-height:150%;"> </p> <p align="left" style="text-align:left;line-height:150%;"> <strong><span style="font-family:宋體;"><span style="font-size:12.0pt;">有效預防病毒</span></span></strong></p> <p align="left" style="text-align:left;text-indent:24.0pt;line-height:150%;"> <span style="font-family:宋體;"><span style="font-size:12.0pt;">根據相關公開信息，新冠病毒需滿足密封環境、長時間暴露、高濃度三個條件才可能發生氣溶膠傳播。而開闊通風環境下，氣溶膠傳播的可能性極低。同時，可以通過實施連續實時的PM2.5</span>監測，提前對顆粒物濃度較高地區實施消毒、噴霧等作業，進一步降低風險的發生。為此，四川瞭望將密切注意顆粒物濃度變化趨勢，并積極保障各顆粒物監測設備的正常運行。</span></p> <p align="left" style="text-align:left;text-indent:24.0pt;line-height:150%;"> <span style="font-family:宋體;"><span style="font-size:12.0pt;">而個人面對氣溶膠傳播，只需佩戴N95</span>（KN95</span>）及以上級別口罩或醫療口罩，勤洗手多通風，不去人員密集場所等個人防護措施，就可以最大限度地降低病毒傳染風險。</p> <p align="left" style="text-align:left;line-height:150%;"> </p> <p align="left" style="text-align:left;line-height:150%;"> <strong><span style="font-family:宋體;"><span style="font-size:12.0pt;">實現人與自然地和諧共處才是長久之計</span></span></strong></p> <p align="left" style="text-align:left;text-indent:24.0pt;line-height:150%;"> <span style="font-family:宋體;"><span style="font-size:12.0pt;">此次新冠病毒來勢洶洶，一方面我們為所有在此次疫情中不幸遇難的患者惋惜，一方面也要反思，這場疫情何嘗不是大自然給我們敲響的一次警鐘？</span></span></p> <p align="left" style="text-align:left;line-height:150%;"> <span style="font-family:宋體;"><span style="font-size:12.0pt;">只有我們改變一些錯誤的做法，停止過渡開發自然資質、停止污染、停止食用野生動物，嚴格執行生態環境的監測監管與治理，相信才能長久地保證我們人類地發展。</span></span></p> <p> </p> </div></div>  <div class="e_box
