Tóm tắt

Mức độ hạt mịn (PM2.5) đã giảm tại Mỹ trong vài thập kỷ qua. Mục tiêu của chúng tôi là đánh giá tài liệu hiện tại để định hình mối liên hệ giữa PM2.5 và sức khỏe xấu ở mức độ tiếp xúc thấp. Chúng tôi đã xem xét 26 bài báo nghiên cứu mối liên hệ giữa tiếp xúc ngắn hạn và dài hạn với PM2.5 và tỷ lệ bệnh lý cũng như tử vong liên quan đến tim phổi. Có bằng chứng cho thấy rằng những mối liên hệ này mạnh mẽ hơn ở mức độ thấp hơn. Tuy nhiên, vẫn tồn tại một số hạn chế về phương pháp và diễn giải liên quan đến các nghiên cứu về mức PM2.5 thấp, do đó cần có sự phát triển phương pháp tiếp theo. Có sự đồng thuận mạnh mẽ giữa các nghiên cứu rằng tác động của ô nhiễm không khí lên sức khỏe tiêu cực vẫn còn có thể quan sát thấy ở nồng độ thấp, ngay cả khi thấp hơn nhiều so với tiêu chuẩn hiện tại của Mỹ. Những phát hiện này cho thấy tiêu chuẩn của Mỹ cần được xem xét lại, vì việc cải thiện chất lượng không khí có khả năng mang lại lợi ích cho sức khỏe cộng đồng.
