    1. Tại Việt Nam, Tổ chức Y tế thế giới (WHO) coi ô nhiễm không khí là một trong những nguyên nhân gây ra gánh nặng bệnh tật và tử vong hàng đầu. Có khoảng 6/10 bệnh có tỷ lệ chết cao nhất tại Việt Nam là những bệnh liên quan đến không khí.
      
    2. Tuy nhiên, việc sử dụng khẩu trang chỉ là một giải pháp tình thế. Theo TS Hoàng Dương Tùng, để hạn chế ô nhiễm bụi PM2.5 cần hướng tới giải quyết tận gốc. Nguyên nhân gây ra ô nhiễm bụi mịn PM2.5 được xác định từ các nguồn sản xuất, giao thông, xây dựng, sinh hoạt... Trong đó bốn ngành gồm sắt thép, nhiệt điện, xi măng, hóa chất đã gây ra 80% lượng ô nhiễm từ các nguồn ô nhiễm điểm.

    1. Negative values included when assessing air quality In computing average pollutant concentrations, EPA includes recorded values that are below zero. EPA advised that this is consistent with NEPM AAQ procedures. Logically, however, the lowest possible value for air pollutant concentrations is zero. Either it is present, even if in very small amounts, or it is not. Negative values are an artefact of the measurement and recording process. Leaving negative values in the data introduces a negative bias, which potentially under represents actual concentrations of pollutants. We noted a considerable number of negative values recorded. For example, in 2016, negative values comprised 5.3 per cent of recorded hourly PM2.5 values, and 1.3 per cent of hourly PM10 values. When we excluded negative values from the calculation of one‐day averages, there were five more exceedance days for PM2.5 and one more for PM10 during 2016.

    1. China has slapped millions of dollars worth of fines on alleged offenders for violating anti-pollution rules, according to state media.

      Worth noting that another motivation for innovation is the growing repricusions of the externalities of legacy industries and companies. This is encouraging investment in sustainable solutions and opening the door for new way business who's costs are lower becuase their impact on the environment is lower.
