LITTLE Kwok Yu-hin is a victim of the territory's filthy air.
And the six-year-old will have to learn to cope because the dirt will always be there, said his mother, Kwok Chak Lai-wa, as she took him to the doctor in Kwun Tong yesterday.
Yu-hin was born with a weak respiratory system and his allergies cause coughing fits when dry weather raises dust levels.
'The doctor said his lungs would get stronger after he reached five and now he is six, so I think he has stronger resistance than before,' said 33-year-old Mrs Kwok, adding, however, that Yu-hin had been coughing for the last few days.
'I can't make him stay at home whenever the air is bad. He has to get used to this kind of weather,' added Mrs Kwok, who lives in Sai Kung.
Meanwhile, the Environmental Protection Department yesterday calculated the air pollution index for industrial Kwun Tong at 82 - 'moderate' - slightly lower than the previous day's record level for the year.
