			<h1><strong>Phương pháp lấy và phân tích mẫu khí thải</strong></h1><p data-start="252" data-end="597">Việc thu mẫu và phân tích khí thải công nghiệp là một trong những hoạt động quan trọng trong công tác <strong data-start="354" data-end="401">quan trắc môi trường và kiểm soát phát thải</strong>. Quá trình này giúp xác định chính xác thành phần, nồng độ và tải lượng các chất ô nhiễm phát sinh từ các nguồn thải như lò hơi, lò đốt, hệ thống sản xuất công nghiệp hoặc các thiết bị xử lý khí.</p><p data-start="599" data-end="846">Các phương pháp thu mẫu và đo khí thải hiện nay được xây dựng dựa trên các hệ thống tiêu chuẩn quốc tế và quốc gia như <strong data-start="718" data-end="757">TCVN, ISO, US EPA Method, JIS và AS</strong>, đảm bảo tính chính xác, khả năng so sánh dữ liệu và đáp ứng yêu cầu quản lý môi trường.</p><p data-start="599" data-end="846"><strong>PHƯƠNG PHÁP THU MẪU VÀ ĐO
