Emiss{\~o}es de gases por ve{\'{\i}}culos automotores
comprometem significativamente a qualidade do ar na Regi{\~a}o

posterior ao evento, e a concentra{\c{c}}{\~a}o de poluentes
atmosf{\'e}ricos na Regi{\~a}o Metropolitana do Vale do
Para{\'{\i}}ba. Os resultados das concentra{\c{c}}{\~o}es de
CO, O3, NO, NO2 e SO2 foram avaliados na forma de ciclos diurnos e
m{\'e}dias di{\'a}rias comparando os anos de 2017 e 2016 (sem
greve) com 2018 (com greve) durante o mesmo per{\'{\i}}odo. Para
representar diferentes condi{\c{c}}{\~o}es de
exposi{\c{c}}{\~a}o {\`a}s diferentes fontes veiculares, foram
escolhidas quatro esta{\c{c}}{\~o}es de monitoramento da
qualidade do ar da CETESB: S{\~a}o Jos{\'e} dos Campos, S{\~a}o
Jos{\'e} dos Campos - Jardim Sat{\'e}lite, Taubat{\'e} e
Guaratinguet{\'a}. Neste estudo tamb{\'e}m foi-se empregado o
modelo Weather Research and Forecasting with Chemistry, sistema de
modelagem da atmosfera com a finalidade de proporcionar
entendimento a cerca da precis{\~a}o do modelo sobre o
per{\'{\i}}odo de estudo sem a entrada for{\c{c}}ada dos dados
da CETESB. Durante o per{\'{\i}}odo da greve, ocorreu
redu{\c{c}}{\~a}o intensa nos poluentes prim{\'a}rios avaliados
(sendo os maiores valores obtidos para S{\~a}o Jos{\'e} dos
Campos: NO - 220%, SO2 - 130%, NO2 - 130%), diretamente associados
{\`a} emiss{\~a}o veicular. Houve aumento de oz{\^o}nio (com
maior valore tamb{\'e}m obtido para a cidade de S{\~a}o
Jos{\'e} dos Campos: 554%) o qual esta diretamente relacionado a
diminui{\c{c}}{\~a}o de NO. ABSTRACT: Pollution becomes one of
the factors that most affect the populations quality of life,
causing damage to human health and the environment. Gas emissions
from motor vehicles compromised with the quality of the
Metropolitan Region of Vale do Para{\'{\i}}ba, releasing large
amounts of carbon monoxide, nitrogen oxides (which are the
precursors of tropospheric ozone) and sulfur dioxide. Brazilian
epidemiological studies understand that gases and particulate
materials are responsible for the incidence of allergic diseases
and bronchial asthma in a significant portion of the population.
The present study demonstrates a direct relationship between heavy
vehicle traffic and, consequently, light vehicles during a period
from May 21 to May 31, 2018, on trucks between May 21 and 31,
2018, as well as a previous week and one week after the event, and
the concentration of air pollutants in the Metropolitan Region of
Vale do Para{\'{\i}}ba. The results of the analysis of CO, O
textubscript 3, NO, NO textubscript 2 and SO textubscript 2 were
used in the form of day cycles and social media compared between
the years 2017 and 2016 (without interruption) with 2018 (with
strike) during the same period. To select different exposure
conditions for different vehicle sources, four CETESB quality
monitoring stations were selected: S{\~a}o Jos{\'e} dos Campos,
S{\~a}o Jos{\'e} dos Campos - Jardim Sat{\'e}lite, Taubat{\'e}
and Guaratinguet{\'a}. The Meteorological Survey and
Meteorological Model with Chemistry was also used in this study,
an atmosphere modeling system using criteria of understanding and
approximation of model precision over the study period without
forced data entry from CETESB. During the strike period, there was
an intense reduction in the primary pollutants evaluated (the
highest values obtained for S{\~a}o Jos{\'e} dos Campos: NO -
220 %, SO textsubscript 2 - 130 %, NO textsubscript 2 - 130 %),
directly associated with vehicular emission. There was an increase
in ozone (with higher value also obtained for the city of S{\~a}o
Jos{\'e} dos Campos: 554 %) which is directly related to a
decrease in NO.",
