VOLATILE ORGANIC COMPOUNDS leading to a decrease in the burning of fossil fuels like diesel fuel, which reduces VOC and NOx emissions, particulate emissions, and dust. Volatile Organic Compounds (VOCs) are toxic or or carcinogenic, as well as creating photochemical fumes in the presence of sunlight, damaging the environment. g����L �ف����8��1Ll�8����TfpT�����n���٤���9�ٜ����u�M�7G��$/L�5�R���R�I���_��iH�ʤ������9IN����l����&=����_|?��l6���`���oҸ�e߆��| k3��Go�X�i��_Ǻ�Sݟ}Re�1�{�m߷�ݗ�O�G=%U�&g�H�֛P{Ԃ��Q�B]d�C�+���Ŏ:Χ��w��o���g �2�Ρ���.����*��[�W�Wh�������������B;j-���*�Bs�{���d�`���"�,r���"KNN�rp�t�t�t�t�t�t�t�t�t�t�t��]�w���S�)�z VOCs are a class of chemicals that are volatile (evaporate easily) and are organic compounds (contain carbon atoms).
